DOOM Eternal but Doomguy is a Crab [Challenge]

Doom Eternal but Doomguy can only move side to side. Moving forward and backward has been removed. Some parts you couldn't progress through without "W" so I changed it to "N" for mantling over surfaces as it was far away from my hand that I wouldn't press it by accident. This is a lot harder than it looks! If you have any more ideas for challenges, put down your comments!
